a1bca4ba - [clang] Make tests write to /dev/null if output is not needed (#135242)

[clang] Make tests write to /dev/null if output is not needed (#135242) We execute tests in read only environment which leads to test failure when tests try to write to the current directory. Either they should write to a temporary directory or not write if output is not needed. Fallback from #134717
